CORRECTIONS
The first upload of this video had some serious audio issues. Sorry! It broke when the video was render and because it was only in the middle I didn't spot it once it had uploaded.
At 07:45 I imply that you might start dealing from the bottom of the deck (obviously I would never dream of such a thing). But the structure is the same as dealing from the top. It was just easier to see from the 'bottom' of the face-up cards.
14:01I am inconsistent with "second card in" and "first card in". In both cases I mean the second card along. Which is the first card 'in'.
Let me know if you spot any mistakes in this version!

Thanks to my Patreon supporters who I used to justify spending several weeks learning how to do a faro shuffle. I'm meant to be writing a new book you know. So, thanks a lot.
